WSUS: Clients fail to update with error code 0x80190194

  • [アーティクル]

Here's a great tip from Rob Coffey, a real life WSUS support engineer from North Carolina.  We've seen reports of this occurring if you upgrade to WSUS Service Pack 1 and then remove the SP although I haven't been able to confirm this myself.  If you have a bunch of clients trying to get updates and failing with a 0x80190194 error then this may be something to check:

========

Issue: When checking for updates, clients may all fail with a 0x80190194 error.

Cause: This can occur if the selfupdate virtual directory has been removed or is missing from the Default Web Site.

Resolution: To resolve this issue we will need to reconfigure the selfupdate virtual directory.  To do this:

  1. Open the IIS Manager console
  2. Drill down to the Default Web Site, right click it and select New -> Virtual Directory
  3. For the alias use Selfupdate and for the path point to the Selfupdate directory.  It should be something like C:Program FilesUpdate ServicesSelfupdate.
  4. Forward through the wizard selecting all the defaults.

Once your done test it out - you should be able to successfully get updates now assuming everything else is working properly.

More Information: The client starts its detection cycle by checking if it's running a compatible version of the client prior to talking to the WSUS server.  This is done by downloading https://wsusservername/selfupdate/wuident.cab, therefore if the selfupdate virtual directory has been removed or is missing then the clients will fail with the 0x80190194 error when attempting to check for the wident.cab file.

========

Thanks Rob!

    I have a similar problem. Using Win7 Ultimate 64-bit, I uninstalled SP1. Attempting to reinstall SP1 gives this error, though I never installed IIS and have never heard of WSUS.
